Read before use

This document contains important technical and safety information about the device, its safety use and installation.
⚠CAUTION! Before beginning the installation, please read this guide and any other documents accompanying the device carefully and completely. Failure to follow the installation procedures could lead to malfunction, danger to your health and life, violation of the law or refusal of legal and/or commercial guarantee (if any). Allterco Robotics EOOD is not responsible for any loss or damage in case of incorrect installation or improper operation of this device due to failure of following the user and safety instructions in this guide.

Product Introduction

Shelly® is a line of innovative microprocessor-managed devices, which allow remote control of electric circuits through a mobile phone, tablet, PC, or home automation system. Shelly® devices can work standalone in a local Wi-Fi network or they can also be operated through cloud home automation services. Shelly Cloud is a service that can be accessed using either Android or iOS mobile application, or with any internet browser at https://home.shelly.cloud/. Shelly® devices can be accessed, controlled and monitored remotely from any place where the User has internet connectivity, as long as the devices are connected to a Wi-Fi router and the Internet. Shelly® devices have embedded Web Interface accessible at http://192.168.33.1 when connected directly to the device access point, or at the device IP address on the local Wi-Fi network. The embedded Web Interface can be used to monitor and control the device, as well as adjust its settings.
Shelly® devices can communicate directly with other Wi-Fi devices through HTTP protocol. An API is provided by Allterco Robotics EOOD. For more information, please visit: https://shelly-api-docs.shelly.cloud/#shelly-family-overview.
Shelly® devices are delivered with factory-installed firmware. If firmware updates are necessary to keep the devices in conformity, including security updates, Allterco Robotics EOOD will provide the updates free of charge through the device embedded Web Interface or Shelly Mobile Application, where the information about the current firmware version is available. The choice to install or not the device firmware updates is user’s sole responsibility. Allterco Robotics EOOD shall not be liable for any lack of conformity of the device caused by failure of the user to install the provided updates in a timely manner.
Control your home with your voice
Shelly® devices are compatible with Amazon Alexa and Google Home supported functionalities. Please see our step-by-step guide on: https://shelly.cloud/support/compatibility/.
Shelly® Pro Series
Shelly® Pro series is a line of devices suitable for homes, offices, retail stores, manufacturing facilities, and other buildings. Shelly® Pro devices are DIN mountable inside the breaker box, and highly suitable for new building construction. All Shelly® Pro devices can be controlled and monitored through Wi-Fi and LAN connections. Bluetooth connection can be used for the inclusion process.
Shelly® Pro 2 (the Device) is a DIN rail mountable 2-circuit smart relay. Enhanced with the second generation firmware flexibility and LAN connectivity, it provides the professional integrators with much more options for end customer solutions.

Installation Instructions

⚠ CAUTION! Danger of electrocution. Mounting/installation of the Device to the power grid has to be performed with caution, by a qualified electrician.
⚠ CAUTION! Danger of electrocution. Every change in the connections has to be done after ensuring there is no voltage present at the Device terminals.
⚠ CAUTION! Use the Device only with a power grid and appliances which comply with all applicable regulations. A short circuit in the power grid or any appliance connected to the Device may damage the Device.
⚠ CAUTION! Do not connect the Device to appliances exceeding the given max load!
⚠ CAUTION! Connect the Device only in the way shown in these instructions. Any other method could cause damage and/or in- jury.
⚠ CAUTION! Do not install the device at a place that is possible to get wet.
⚠ CAUTION! Allow at least 10 mm of space around each Pro device if you expect currents higher than 5 A per channel.
⚠ RECOMMENDATION Connect the Device using solid sin- gle-core cables with increased insulation heat resistance not less than PVC T105°C.
Before starting installing/mounting the Device, wire check that the breakers are turned off and there is no voltage on their terminals. This can be done with a phase meter or multimeter. When you are sure that there is no voltage, you can proceed to connecting the cables.
Connect the N terminal to the Neutral cable and the L terminal to the Device power supply circuit breaker as shown on Fig. 1. Connect the first load circuit to the O1 terminal and the Neutral cable. Connect the I1 terminal to the first load circuit breaker. Connect the second load circuit to the O2 terminal and the Neutral cable. Connect the I2 terminal to the second load circuit breaker.
Two different phases can be used for the two load circuits and a third one for the Device power supply circuit. Connect the two switches/buttons to the S1 and S2 terminals and the Device power supply circuit breaker.
⚠ RECOMMENDATION: For inductive appliances that cause voltage spikes during switching on/off, such as electrical motors, fans, vacuum cleaners and similar ones, RC snubber (0.1µF / 100 Ω / 1/2 W / 600 VAC) should be connected parallel to the appliance. The RC snubber can be purchased at https://shop.shelly.cloud/rc-snubber-wifi-smart-home-automation.

Initial Inclusion

If you choose to use the Device with the Shelly Cloud mobile application and Shelly Cloud service, instructions on how to connect the Device to the Cloud and control it through the Shelly App can be found in the “App Guide”.
The Shelly Mobile Application and Shelly Cloud service are not conditions for the Device to function properly. This Device can be used stand-alone or with various other home automation platforms and protocols.”
⚠ CAUTION! Do not allow children to play with the buttons/switches connected to the Device. Keep the Devices for remote control of Shelly (mobile phones, tablets, PCs) away from children.
